September 4th 2026, Jongia opens its doors!

On Friday, September 4, Jongia Mixing Technology will open its doors to invited guests and (former) colleagues. It’s a milestone we’d like to celebrate with you.

Since joining the international group under the De Dietrich flag in 2024, Jongia has entered a new phase — and that calls for a fitting celebration.

During the open day, we’ll take you through our complete process: from design to production and testing of our agitators. We will also present a selection from the De Dietrich portfolio, featuring products that combine proven expertise with applications in the chemical and pharmaceutical industries.
